[[Asuma Sarutobi]] coupled these knives with his [[taijutsu]] skills to [[Flying Swallow|devastating effect]], such that he could take out nine [[Otogakure]] ninja in a matter of seconds. When infused with [[Wind Release|wind-natured chakra]], they can easily pierce and cut through stone and even metal. The knives' sharpness and effectiveness can also be maximised if the person has better control of their chakra as seen with how Asuma was training [[Sora]] and [[Naruto Uzumaki]] in focusing their wind chakra into their kunai. After Asuma's death, the blades come into [[Shikamaru Nara]]'s possession. When infused with his shadow chakra, they can [[Shadow Imitation Shuriken Technique|immobilise anyone whose shadow it pierces]].

A Chakra Blade (チャクラ刀, Chakura Tō) is an highly uniquely-designed trench knife. These blades are worn like brass knuckles, but each one has a sharpened zigzag "tooth" over each knuckle, and a blade coming out of one end.
